This invention relates to improvements in concrete tank construction and more particularly to concrete tanks suitable for the support and insulation of lead electrolyticcells.

The invention has for its object the provision of a concrete tank construction composed of a plurality of interchangeable units which may be molded or cast separately and then assembled together at any desired location.

A further object'of the invention is to provide a support forlead electrolyticcells which will be more durable and resilient than the wooden supports in general use at present and at the same time more easily assembled and re-. paired than monolithic concrete construction.

Other objects of the invention will appear from the detailed description below.

The invention broadly comprises a tank, vat or container constructed of a small number of reinforced concrete units, namely: bottom'units, end units and side units, molded into shapes suitable to be assembled into an individual tank; or, by using a sidewall of a tank as a partition commonto two tanks, into a series of tanks or a tank'comprising a plurality of compartments. o

The invention will be more particularly described with reference, for the purpose of illustration, to the accompanying drawings, in which:

Fig. 1 is a perspective viewin-partial section of an embodiment of the invention in which a series of tanks, or as it may be equally well expressed, atank subdivided into a plurality of compartments, is provided as a support for a series of lead electrolytic cells; I

Fig. 2 is a partial plan of the embodiment of Fig. 1; j

Fig. 3 is an end elevation in partial section;

Fig. .4 is an end elevation; and

Fig. 5 is a section on the line 5-5 of Fig. 3.

The main units of the tank construction are the base 1,-theside'units 2,-the partition units 3, and the ends units 4: and 5.

The base unit 1' comprises a rectangular reinforced concrete slab,'provided with'slots 6 adapted to receive the lower edges of side units 2 and partition units 3; it'is also provided with a plurality of leak holes 7 so spaced. as to avoid exposing any'metal rein- 1929. Serial No. 345,544.

forcement, and carries openings 8 for draining the contents of the cells. The leak holes 7' ensure the prompt detection of any leaks in the lead cell.

The side units 2 consist of rectangular reinforced concrete slabs adapted to fit into the slots 6' of the base member and provided at each end with a plurality of projecting threaded rods 9. These rods are securely embedded in the concrete and may advantageously extend lengthwise through the side units and project at each end thereof, thus serving both to reinforce the side members and to securely holdthe construction together. The rods are adapted to pass through corresponding holes suitably cored in the end units to be described.

The partition units 3 consist of rectangular reinforced concrete slabs substantially identical with the side units 2 described above, differing principally in that the side units are advantageously provided. on their outer sides .with reinforcing elements 10.

with. lateralextensions 11 adapted to fit into notches formed by corresponding lateral extensions on the adjacent end units and pro 'videdwithholes adapted to receive the projecting threaded rods 9 of the side and partition units. .The' end units may be provided with holes 12 and notches 13 for the introduction and discharge of electrolyte. End units 5 are provided with the lateral extensions 11 only on one side. i

In assembling the construction the side units 2' and partition units 3 are positioned in the corresponding slots 6 of base unit 1,

and the end units land 5 are slipped over the projecting threaded rods 9 so that the partition units3 are supported at each end by the interlocking projections 11 of two adjacent end units. V

The joint thus formed is covered with an iron plate 14 provided with holes spaced to correspond to and receive the rods 9 The plates 14 are then drawn up tight to the interlocking projections by means of nuts on the threaded ends of the rods 9. The plates 14 thus support that part of the end units not directly supponted by the rods. i

The whole construction is advantageously supported on concrete posts 18. a V a V The advantages of the above described support for lead electrolytic cells include the renewing:
